ABSTRACT: The effects of overrun and glycerol as a cryoprotectant on viability of probiotics in frozen yogurt were investigated. Frozen yogurt was prepared with different types of probiotics (Lactobacillus acidophilus and Bifidobacterium lactis) along with normal yogurt starter culture (Streptococcus salivarius ssp. thermophiles and L. delbrueckii ssp. bulgaricus). Frozen yogurt mixture was supplemented with 1.5, 3 and 4.5% glycerol and was frozen with 60, 80 and 100% overrun. Viability of probiotic bacteria after freezing and during storage period of 12 weeks was investigated. Supplementation of glycerol in the mixture has improved the survival of L. acidophilus and B. lactis during the frozen storage. At the end of storage period the overall loss in viability of the L. acidophilus with 60, 80 and 100% overrun was 1.81, 1.96 and 2.24 log CFU/g, respectively. The B. lactis viability loss with 60, 80 and 100% overrun was 2.11, 2.26 and 2.26 log CFU/g, respectively. All the supplemented probiotics maintained the minimum concentration of 107 CFU/g in frozen yogurt during frozen storage, which is required for beneficial health effects in the host.

ABSTRACT: The growth performance and metals depuration abilities of Zn+Pb+Ni stressed five fish species viz. Cirrhina mrigala, Hypophthalmichthys molitrix, Labeo rohita, Ctenopharyngodon idella and Catla catla were studied under composite pond culture conditions. All fish species were stressed with metals mixture at their 1/3rd LC50 for one month. After stress, the fish were grown in ponds under composite culture conditions for 120 days to realize their growth and metals depuration potentials when grown in stress-free environment. Among treated fish, C. mrigala exhibited significantly better growth, followed by L. rohita, C. idella, H. molitrix and C. catla while growth in control fish followed the order: C. catla ≥ L. rohita > C. mrigala > C. idella > H. molitrix. Both control and treated fish species displayed significant variations in their weight, length, condition factor and specific growth rates that correlated positively (p<0.01) with water temperature and feed conversion efficiency (FCE). Rearing of treated fish in metals deprived environment caused variable retention of selected metals in their body organs as kidney > liver > skin > muscle > fins ≥ gills ≥ bones. C. idella retained significantly higher metals in its body, followed by C. catla and H. molitrix with non-significant differences. Pb retention was significantly higher in fish body, followed by Zn and Ni. The liver of treated fish showed significantly higher depuration of metals (94.06%) while it was lowest (66.06%) in bones. C. catla exhibited significantly higher metal's depuration tendency (96.44%), followed by L. rohita (93.11%), C. idella (93.02%), C. mrigala (89.35%) and H. molitrix (82.60%) with significant differences at p < 0.05. The tendency of fish to depurate Pb from its body was significantly higher (177.94%), followed by Zn (131.13%) and Ni (38.26%).
